Replicant » Upstreaming patches

The patches don't compile yet => rebase and make them compile.

Then once I'll have it tested and cleaned up I'll send it upstream.

We also need to sync with Viciouss who is working on similar patches for the GT-N8000: https://github.com/Viciouss/linux/commit/bf6d0a67b7bdc62433c663fe4c2886af8a0af9d2

Edit 1:Fix typo and add device.

It looks like a samsung employee has been submitting midas related patches upstream, including a patch set for audio support: https://patchwork.kernel.org/project/linux-samsung-soc/list/?submitter=7616

It looks like you can test out the audio patch as of today using the sound-5.9-rc1 branch, as is explained here: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg2260833.html

These two midas sound driver patches were applied today:
